There are 63 national parks in the United States, each established to preserve unique landscapes, wildlife, and historical sites for the enjoyment of present and future generations. These parks are managed by the National Park Service, which aims to conserve the scenery and natural and historic objects within the parks. National parks offer a wide range of activities such as hiking, camping, wildlife viewing, and learning about the natural world. Some of the most visited national parks include Great Smoky Mountains, Yellowstone, and Zion, while others like Gates of the Arctic see fewer visitors due to their remote locations. Each national park has its own distinct features and attractions, contributing to the diverse tapestry of protected lands across the country.
